What Causes Low Levels of Absolute Eosinophils?
Low levels of absolute eosinophils are caused by either alcohol intoxication or the over production of certain specific steroids in the body, such as corticosol, as reported by MedlinePlus. Absolute eosinophils are white blood cells that are responsible for dealing with allergies, infections and other medical conditions.
To determine the amount of absolute eosinophils that are present in the body, a blood test is required. A blood sample will be drawn from inside the elbow or from the back of the hand. The blood sample is then sent to a laboratory where it will be placed underneath a microscope and examined. To identify the absolute eosinophils, a dye is added to the sample so that the eosinophils become orange-red granules. This helps to weed out the eosinophils from other cells that may be present in the blood.
Very little medications will influence the outcome of the blood test. Patients should notify medical professionals if they are taking medications like laxatives that contain psyllium, amphetamines, interferon or antibiotics.
The normal range to be expected for absolute eosinophil count is slightly less than 350 cells per microliter. Generally speaking, the test is not to determine a low absolute eosinophil count, but rather a higher than normal count, as this is an indication of the presence of an allergy or an infection.
